A drug company is considering investing $100 million today to bring a weight loss pill to the market. At the end of one year, the firm will know the payoff; there is a 0.50 probability that the pill will sell at a high price and generate $37 million dollars per year of profit forever and a 0.50 probability that the pill will sell at a low price and generate $1 million per year of profit forever. The interest rate is 10%. Suppose the firm decides to wait one year to determine whether the pill will sell at a high price or a low price. The firm will not invest if it learns that the pill will sell at a low price. What is the option value of waiting one year to make the investment?

Question

Quizplus · Accepted Answer

The option value of waiting can be calculated by first determining the present value (PV) of the project under both high and low price scenarios, then weighting these by their probabilities, and finally comparing this weighted average to the immediate investment cost. For the high price scenario, the PV is $37 million / 0.10 = $370 million. For the low price scenario, the PV is $1 million / 0.10 = $10 million. However, since the firm will not invest in the low price scenario, its value is $0 in the decision-making process. The expected value of waiting is thus 0.50 * $370 million + 0.50 * $0 = $185 million. If the firm waits, it avoids the immediate investment of $100 million, so the net value is $185 million - $100 million = $85 million. However, this $85 million is in future dollars, one year from now. To find the option value today, we discount it back one year at the 10% interest rate, which gives us $85 million / (1 + 0.10) = $77.27 million. The option value of waiting, therefore, is the difference between the net value if the firm waits ($77.27 million) and the net present value of investing today. Since the question does not provide the net present value of investing today, we focus on calculating the value of waiting, which involves understanding the expected value of the project if the decision to invest is deferred for a year. Given the provided choices, none directly match the calculated explanation, suggesting a need for recalculating based on the given information and choices. The correct calculation involves the expected profit from waiting and investing only in the high price scenario, discounted back at the given interest rate. The mistake in the initial explanation was in the misinterpretation of how to apply the probabilities and the discount rate to find the option value of waiting. The correct approach involves calculating the expected present value of the project if the decision is deferred, considering only the profitable scenario (since the investment won't proceed in the unprofitable scenario), and then comparing this to the investment cost to find the true option value of waiting.
